Summary
Paperclip: Malicious skills able to exfiltrate and destroy all user data
Details

Summary

An arbitrary code execution vulnerability in the workspace runtime service allows any agent to execute shell commands on the server, exposing all environment variables including API keys, JWT secrets, and database credentials.

Details

A malicious skill can instruct the agent to exploit the workspace runtime service feature, which allows arbitrary shell command execution on the server.

Vulnerable Code Path

  1. Agent calls PATCH /api/projects/{projectId}/workspaces/{workspaceId} to set a malicious runtimeConfig
  2. Agent calls POST /api/projects/{projectId}/workspaces/{workspaceId}/runtime-services/start
  3. Server executes the command via spawn() in server/src/services/workspace-runtime.ts:
const shell = process.env.SHELL?.trim() || "/bin/sh";
const child = spawn(shell, ["-lc", command], { cwd: serviceCwd, env, ... });

The command parameter comes directly from workspace config with no sanitization, allowing arbitrary code execution in the server's process context.

Attack Flow

The attached skill (disguised as a "system health diagnostic") instructs the agent to:

  1. Create a workspace with a malicious runtime command
  2. Start the runtime service to execute the command
  3. The command reads /proc/1/environ and exfiltrates via curl

This successfully exfiltrated the server (not the agent workspace) environment variables.

Variable Value Risk
OPENAI_API_KEY sk-proj-mSoajc... OpenAI API access
BETTER_AUTH_SECRET test-secret-for-dev Auth token signing
PAPERCLIP_AGENT_JWT_SECRET agent-jwt-secret-for-dev Agent JWT signing
DATABASE_URL postgresql://paperclip:paperclip@... Database credentials

PoC

  1. Start the exfil server: bash python3 exfil-server.py

  2. Start Paperclip: bash cd paperclip && pnpm dev

  3. In the Paperclip UI, go to Skills and import the malicious skill by pasting the local path to malicious-skill.md (or host it on GitHub and import via URL)

  4. Create an agent and add the malicious skill to its allowed skills. Assign it a task that triggers skill loading (e.g., "run system diagnostics")

  5. View captured secrets at http://localhost:8888/data or in the terminal running exfil-server.py

    print(f"Exfil server listening on http://0.0.0.0:{port}")
    print("Waiting for data...\n")
    server.serve_forever()

Impact

This is an arbitrary code execution vulnerability. Any user who can install a skill or convince an agent to load a malicious skill can execute arbitrary commands on the Paperclip server. This exposes all server secrets (API keys, JWT signing secrets, database credentials) and could lead to full server compromise.

Mitigation
Architecture and Design

If at all possible, use library calls rather than external processes to recreate the desired functionality.

Mitigation
Implementation

If possible, ensure that all external commands called from the program are statically created.

Mitigation MIT-5
Implementation

Strategy: Input Validation

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
Mitigation
Operation

Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.

Mitigation
System Configuration

Assign permissions that prevent the user from accessing/opening privileged files.

CAPEC-136: LDAP Injection

An attacker manipulates or crafts an LDAP query for the purpose of undermining the security of the target. Some applications use user input to create LDAP queries that are processed by an LDAP server. For example, a user might provide their username during authentication and the username might be inserted in an LDAP query during the authentication process. An attacker could use this input to inject additional commands into an LDAP query that could disclose sensitive information. For example, entering a * in the aforementioned query might return information about all users on the system. This attack is very similar to an SQL injection attack in that it manipulates a query to gather additional information or coerce a particular return value.

CAPEC-15: Command Delimiters

An attack of this type exploits a programs' vulnerabilities that allows an attacker's commands to be concatenated onto a legitimate command with the intent of targeting other resources such as the file system or database. The system that uses a filter or denylist input validation, as opposed to allowlist validation is vulnerable to an attacker who predicts delimiters (or combinations of delimiters) not present in the filter or denylist. As with other injection attacks, the attacker uses the command delimiter payload as an entry point to tunnel through the application and activate additional attacks through SQL queries, shell commands, network scanning, and so on.

CAPEC-183: IMAP/SMTP Command Injection

An adversary exploits weaknesses in input validation on web-mail servers to execute commands on the IMAP/SMTP server. Web-mail servers often sit between the Internet and the IMAP or SMTP mail server. User requests are received by the web-mail servers which then query the back-end mail server for the requested information and return this response to the user. In an IMAP/SMTP command injection attack, mail-server commands are embedded in parts of the request sent to the web-mail server. If the web-mail server fails to adequately sanitize these requests, these commands are then sent to the back-end mail server when it is queried by the web-mail server, where the commands are then executed. This attack can be especially dangerous since administrators may assume that the back-end server is protected against direct Internet access and therefore may not secure it adequately against the execution of malicious commands.

CAPEC-248: Command Injection

An adversary looking to execute a command of their choosing, injects new items into an existing command thus modifying interpretation away from what was intended. Commands in this context are often standalone strings that are interpreted by a downstream component and cause specific responses. This type of attack is possible when untrusted values are used to build these command strings. Weaknesses in input validation or command construction can enable the attack and lead to successful exploitation.

CAPEC-40: Manipulating Writeable Terminal Devices

This attack exploits terminal devices that allow themselves to be written to by other users. The attacker sends command strings to the target terminal device hoping that the target user will hit enter and thereby execute the malicious command with their privileges. The attacker can send the results (such as copying /etc/passwd) to a known directory and collect once the attack has succeeded.

CAPEC-43: Exploiting Multiple Input Interpretation Layers

An attacker supplies the target software with input data that contains sequences of special characters designed to bypass input validation logic. This exploit relies on the target making multiples passes over the input data and processing a "layer" of special characters with each pass. In this manner, the attacker can disguise input that would otherwise be rejected as invalid by concealing it with layers of special/escape characters that are stripped off by subsequent processing steps. The goal is to first discover cases where the input validation layer executes before one or more parsing layers. That is, user input may go through the following logic in an application: <parser1> --> <input validator> --> <parser2>. In such cases, the attacker will need to provide input that will pass through the input validator, but after passing through parser2, will be converted into something that the input validator was supposed to stop.

CAPEC-75: Manipulating Writeable Configuration Files

Generally these are manually edited files that are not in the preview of the system administrators, any ability on the attackers' behalf to modify these files, for example in a CVS repository, gives unauthorized access directly to the application, the same as authorized users.

CAPEC-76: Manipulating Web Input to File System Calls
